FLUSHlNG-VALVE.

SPECIFICATION forming part of Letters Patent No. 661,885, dated November13, 1900.

' Application filed April 9, 1900. s mi n 12,153. on model-J To all whmnit may concern.-

Be it known that I, FRED WILLIAM MEYER, of Louisville, in the county ofJefferson and State of Kentucky, have invented certain new and usefulImprovementsin Flushing-Valves; and I hereby declare that the followingis a full, clear, and exact description thereof, reference being had tothe accompanying drawings, which form part of this specification.

This invention is an improvementin flushing-valves especially adaptedfor use as automatic flushing-valves for waterclosets, for stop andwaste valves for systems of water distribution in buildings, and forvarious other purposes in the arts where such valves can be usefullyemployed.

The invention consists in the novel construction of the valve shown inthe drawings and hereinafter described with reference thereto.

In said drawings, Figure 1 is a side elevation of the valve applied tothe bowl of a water-closet. Fig. 2 is an enlarged longitudinal sectionalview through the valve. Fig. 3 is a view of the valve applied to anotherwater-closet fixture. Fig. 4 is a view of the valve applied to otherfixtures. Fig. 5 is a detail.

The valve-casing O is approximately U- shaped, being provided with aninlet-chamber A in its upper leg and anoutlet-chamber B in its lowerleg, the latter being connected with the former by a bend, and at thebend intermediate chambersA and B is a storagechamber D. Within chamberA is a valveseat a, and at the junction of the chambers B and D is anoppositely-facing valve-seat b. The outlet-chamber B has adischarge-opening e, which communicates with a suitable flushing-pipe E,and the inlet-chamber A has an inlet-openingf, which communicates with asuitable water-supply pipe F. Within the chamber A is a valve a, whichis adapted to close against the seat a, and within the chamber D is avalve 1), which is adapted to close against the seat I). The valves a bare substantially parallel, but face in opposite directions, and arerigidly connected, so that as one is opened the other is closed. Asshown, the valve b is mounted on the inner end of a rod G, which extendsthrough a stuffing-box B'iu the outer end of chamber B and ing g, whichextends through the chamber- D, and the valve a is secured to the upperend of casting g by means of a screw g, as

shown, the casting g thus lying transversely of both valves. Thus theparts G, g, and g practically form the valve-stem and are rigidlyconnected, so that they move as one. The stem is thus made in sectionsfor convenience in assembling the parts within the valve-casing, and theouter end of chamber A is closed by a screw-cap A to enable the parts ag to be readily secured in place. A spring H is interposed between a nuth on red G and the outer end wall of chamber B, this spring serving tonormally force the stem inward, so as to normally hold valve 1) open andvalve a closed. In some cases a weighted lever T may be employed tooperate the valvestem, as indicated .in Figs. 2, 3, and 4.. Thestorage-chamber D may be connected by a pipe I to a tank "L in the usualmanner, and the flushing-pipe E may be connected directly to the bowl Jof the closet, if desired, as shown in Figs. 1 and 3, Fig. 1 showing themost direct and preferable connection of the valve to the closet andtank, or the flushing'pipe E may lead to the soil-pipe S, as in Fig. 4.

The closet shown in Fig. 1 has a hinged seatj, which may be providedwith any suitable upholding-springs, (not shown,) but such as are wellknown. This seat is hinged to the bowl, and to the hinge of the seat mayalso be hinged a short bifurcated lever K. It is preferably so hinged tothe seat that the latter can be raised to permit inspection or cleansingof the bowl; but when the seat is lowered beyond the point allowed byits spring the lever K will be rocked forwardly and its upper bifurcatedend will engage the collar or head on the outer end of rod G and pullthe valve-stein outward whenever the seat is pressed downward. Thereuponvalve 1) will be seated and valve ct unseated, and immediately waterwill flow from chamber A through the storage-chamber D into pipe I andup into the tank, and the pressure of the water will now partiallyassist in holding the valve 1) closed. When the pressure on the and inso doing will seat valve t.

seat is relieved, the spring H and the pressure of water on valve a"will unseat valve 1) Thereby the supply of water from pipe F is cut off,and the water collected in the storing-chamber D, pipe I, and tank t'ispermitted to flow back through chambers D and B into the flushing-pipe Eand thence into the bowl, flushing the latter, as is obvious.

Owing to the opposite arrangement of and connection between the valvesct b they are balanced-that is, whenboth are opened the tendency of thewater-pressure to close one valve is countervailed by the tendency toclose the other valve. This facilitates the operation of the valve; butas soon as one valve is seated the whole pressure is exerted thereon andkeeps such valve closed by reason of the exhaust on the opposite side ofthe closed valve.

Fig, 2 shows inlet-valve a closed, and natu rally the pressure of waterin theinlet-cham her A will assist in keeping this valve closed, whileat the same time the water that has accumulated in the storage-chamberescapes freely past the open valve b, while when the seat is depressedand the rod G drawn outward, so as to close valve 1), of course valve 0/is simultaneously opened, and the pressure of the water then in thechambers A and D will be practically neutralized on the valve ct and beexerted wholly on the valve 19' and assist in keeping the latter closed,and as soon as the storage-chamber is full the pressure of the entirehead of water will then be exerted to keep valve 1) closed. This is'oneof.the objects of the construction of my valve and renders the operationthereof very easy, for it is only necessary in order to flush the closetthat sufficient pressure be exerted on the rod G to overcome thepressure of the water against valve 1). As soon as this pressureisovercome and the valve 1) opened the the latter valve, as before.

rushof water past valve 0, will tend to close Thus practically inmyconstruction the head of water is utilized in seating or in holdingseated both valves (1 and b, which is a practical advantage where thedevice is used in connection with water-closets, as owing to theconsequent ease of operation of the valve trembling and jarring of theseat are prevented.

Preferably the chamber B may be provided with a drip-outlet b, that canbe connected by a pipe L, Figs. 3 and 4, with the soil-pipe S or otheroutlet ata point sufiiciently below the chamber B to insure the properdrainage of all water therefrom when the valve (1 is closed. Thusfreezing up of the valve is prevented by draining all water therefrom.

Fig. 3 shows the valve arrangedbelow the closet-floor, and in this casethe collared end 0 of stem G is engaged by the short'arm of anangle-lever T, pivoted on the casing and having a weighted outer end bywhich the stem will be normally forced inward, so as to close valve (1.and open valve 1). This lever T may be connected to the closet-seat, asindicated in Fig. 3, by a chain or cord, so that when the seat isdepressed the valve b will be closed and valve a opened.

In Fig. 4 the valve is shown connected with the piping-0f a house, to beused as a stop and waste valve.

What I claim as new is 1. In a valve, the combination of the inlet andoutlet chambers, and the'intermediate storing-chamber communicatingtherewith, the oppositely-facing valves for closing communicationrespectively between the inlet and storing chambers, and between thestoring and flushing chambers, the stem or casting working in thestoring-chamber and subject at all times and upon all sides to thepressure in said chamber and connecting said valves whereby when onevalve is opened the other is closed, and the valve-rod for displacingthe valves, each of said valves being adapted to be held closed afterbeing seated by the pressure of the water in the casing, substantiallyas and for the purpose described. v

2. -In a valve, the combination of the inlet and outlet chambersarranged side by side, the storage-chain ber communicating with theinner ends of both the inlet and outlet chambers, the oppositely-facingbalanced valves 'for closing communication between the storage-chamberand the inlet and outlet chambers respectively, the rigidtransversely-disposed connection between the valves within thestorage-chamber and unaffected by the pressure of water therein, thevalve-rod extending through the outlet-chamber and connected to theoutlet-valve, a spring on said rod within the outlet-chamber forunseating the outlet-valve, and exterior means for operating said rod;with the supply-pipe communicating with the inlet-chamber, aflushing-pipe communicating with the outletchamber, and the tankcommunicating with the storage-chamber, all so arranged that thepressure of the water on the valves when both are opened is balanced,but will hold either valve to its seat after it is closed, for thepurpose and substantially as described.

3. In a flushing-"alve, the combination of a U-shaped casing providedwith an inletchamber in one leg communicating witha water-supply, anoutlet-chamber in its other leg communicating with a flushing or wastepipe, and a storage-chamber communicating with both the inlet and outletchambers; with the oppositely-facing balanced valves for closingcommunication between the storage-chamber and inlet and outlet chambersrespec- :tively, the casting in the storage-chamber and subject at alltimes and upon all sides to the pressure in said chamber detachablyconnected to the face of one valve and to the back of the other and thevalve-rod extending through the outlet-chamber and through theoutlet-valve attached to said casting, and connections whereby said stemis operated IIO so as to close the outlet and open the inlet valve,substantially as described and for the purpose set forth.

L. The combination of a U-shaped casing having an inlet-chamber in oneleg and an outlet-chamber in its opposite leg and a storage-chambercommunicating with both legs at the bend of the casing, theoppositely-facing valves for closing communication between thestorage-chamber and the inlet and outlet chambers respectively, adetachable connection between said valves within the storage-chamber andsubject at all ti mes and upon all sides to the pressure in saidchamber, the rod extending through the outletchamber but rigidlyattached to said detachable connection aud a spring on said rod foropening the outlet-valve and closing the inlet-valve, and means forforcibly opening the inlet-valve and simultaneously closing theoutlet-valve, each valve being held closed, after being seated, by thewater-pressure, for the purpose and substantially as described.

5. In a water-closet valve, the combination of the water-closet bowl,the tank, and the flushing-valve interposed between the bowl and tankhaving a U -shaped casing provided with an inlet-chamber in one legcommunicating with a Water-supply, an outlet-champressure in saidchamber detachably connected to the face of one valve and to the back ofthe other and the valve-rod extending through the outlet-chamber andthrough the valve between the outlet and storage chambers and attachedto said casting and connections whereby said stem is operated from thecloset-seat to open the inlet and close the outlet valve, and a springfor opening the outlet-valve and closing the inletvalve, allsubstantially as and for the purpose described.
